OIL-CAKE FORM ER.

SPECIFICATION forming part of Letters Patent No. 621 ,904, dated March 28, 1899.

Application filed October 24, 1898. fierial No. 694,422. (No model.)

To all whom it may concern.-

Be it known that I, THOMAS DE ARMON, a citizen of the United States, residing at Dayton, in the county of Montgomery and State of Ohio, have invented certain new and useful Improvements in Oil-Cake Formers; and I do hereby declare that the following is a full, clear, and exact description of the invention, which will enable others skilled in the art to which it appertains to make and use the same, reference being had to the accompanying drawings, and to the letters of reference marked thereon, which form a part of this specification.

This invention relates to machines for forming oil-cake, and is an improvement of the oilcake former patented by myself July 13, 1897, No. 586,353.

The object of the said invention is to improve the means for actuating the movable former-plate, or, more definitely, means for actuating the steam piston or ram upon which said former-plate is mounted. In the patent above referred to these means consist of exterior pipes,valves, and valve-actuatin g rods, which have been found to be more or less detrimental to the appearance of the machine and not altogether reliable in their various operations. In the present invention the means for admitting the steam and for controlling the admission of steam for driving said ram obviate the above objections and greatly simplify the mechanism; therefore are much preferred.

As much of the machine is not involved in the present invention, it is not thought necessary to embody a full description thereof in the specification to follow. For example, the meal-carrier and the driving mechanism controlling it are substantially the same and the timing of the several movements have not been changed. For amore extended description of these parts the said patent may be referred to. ,Of the accompanying drawings, Figure 1 is a side elevation of my oil-cake former. Fig. 2 is a vertical mid-sectional view of the steamcylinder and valve-chest, the valve appearing in section and a portion of the steam-ram appearing in elevation. Fig. 3 is an eleva tion of the steam with valve and chest removed.

-ent hereinbefore referred to.

In a detailed description of the invention similar letters of reference indicate corresponding parts.

The horizontally-reciprocating meal-carrier A moves upon side supports or guides A on each side of the machine and is actuated in its movements from the crank-shaft A" by the means fully described in the Letters Pat- The meal is carried forward by said carrier and deposited into the lower or movable member B of the cake-former plates. This plate is moved upwardly with the meal therein, and the said meal is formed into cake by being compressed against the upper or stationary former-plate B. The movable former-plate is mounted on a steam piston or ram 0, which moves in a steam-cylinder O. Y

D designates a steam-chest mounted on the side of-the cylinder and communicating with said cylinder through ports E and F, which are steam-inlet ports, and also port H, which is an exhaust-port for said cylinder. I designates a slide-valve controlling said ports. When the said valve is elevated, as shown in Fig. 2, the steam first enters the cylinder through port F, which gives the ram 0 its initial movement. The steam entering said port continues to raise said ram until the latter uncovers port E. When this portis thus uncovered, the supply of steam to the cylinder becomes augmented, and the ram. is thereby given greater force in its movement at the point where the compression of the cake begins. The valve I is connected to the valverod 1, which has a pivotal connection with a hand-lever J, having a fulcrum at J. This hand-lever is manually raised to move the valve to the position to admit the steam. It will thus be seen a single valve controls the entire inlet of steam to the cylinder, thereby dispensing with all external appliances. The valve-chest D is supplied through a pipe conheating in the opening K, which communicates with an auxiliary chamber K in the wall of the cylinder. The said chamber K is shown in broken lines in Figs. 2 and 3. The said chamber communicates with the upper portion of the chest through a port L. (Shown in dotted lines in Fig. 2 and in full lines in Fig. When the ram has been driven to the limit of its upward movement, the valve ICC) I is let down to a position which brings the recess II therein over the port F and exhaustport II, and the said port F becomes an exhaust-port, through which the cylinder exhausts to port 11. The valve-operating lever J is locked against any upward movement during the period in which the meal-carrier A is moving forward to deliver its load into the former-plate B. The mechanism for looking said lever is fully described in my patent hereinbefore referred to.

Having fully described my invention, I claim In an oil-cake former, the combination with a stationary, and a movable former-plate, a ram upon which said movable former-plate is mounted, a steam-cylinder having a lower steam-passage F through which the initial steam-pressure is admitted to raise said ram, and upper steam-passages E E located midway of the cylinder and through which additional steam-pressure is admitted to further elevate the ram after said ram uncovers the said passages E E, and an exhaust-passage II in the wall of the cylinder, of a verticallymovable valve having two ports adapted to be moved to positions to simultaneously admit to said passages F and E E, and an exhaust-passage H in said valve which effects a communication between the passage F and the exhaust-passage H when the valve is moved to the position to shut off the admission of steam to the passages F E E, substantially as and for the purposes specified.

In testimony that I claim the foregoing as my own I hereto aflix 'my signature in presence of two witnesses.

THOMAS DE ARMON.
